Application med Marcher; 19 24. Serial No. 702,215; f f I I To all witom it may concern: i L Be it known that we, CHARLES H. BRADLEY and FRANK D. ALLEN, citizens of the United States; residing at Cleveland, in the county 5 of Cuyahoga and State of Ohio, have in-i vented certain new anduseful Improvements in separable Fasteners, of whichthe following is a specification- Our invention, relates to improvements" in 1 separable fasteners, the present embodiment of the invention being in-the -specific form of a separable-cuff button or link for use in fastening together cuffs and wherein the cuff buttons remain in thebuttonholes when the parts areseparatedin order'toopen' or unfasten the cuff. q i

The primary object of the invention is to provide a'generally improved separable or two part fastener of the type indicatecL which will be exceedingly simple in cons'trucof manufacture," and eflicient in "tion, cheap use i v v A, further and important object is the provision of a cuff connecting link orbutton of'this class in which the connecting parts the provision 'of a fastener of this type in which the parts are positively locked'when e in their connected positionandare positively unlocked when the coupling members or buttons are moved to -an"unlockedposition-v relative to each other! A still further object is the provision of a 9., separable cuff button of improved formbet ter adapted tobe retained within. and se cure the cuff when' connected, as well as adaptedto-permit of relative movement to each other when 'itflis desired to connect ordisconne'ct thesameg; g .1

'lVith the above mentioned andother ends in view, theinvention'consists in the-novel construction, arrangement and-' combination of parts, hereinafter described,illustrated in one of its embodiments in the.accompanying drawings, and particularly the appended claims.

Referring to the drawings, forming apart 7 of this specification, Figure I is'an enlarged elevation of a two-part'separable cuff or, stud side of -the separablebutton." i

elements oribars 2 when theitw obutton's arejlle i particularly'as a means of causing the spring I action of such locking elements or arms 2* to contact with the inclined wedge-shaped portions ofthe stud 1 as hereinafter referred to, to force the two buttons apart,

two oppositely arranged or inclined rela-- tively flat portions-1 are formed 1I1t6l'-' mediate the bar receiving slots or recesses 1 so that when the buttons are twisted a quarter turn relative to each other, as shown in Fig. 3, the bars 2 will ride out of the slots 1* and coming into contact with the inclined or wedge=shaped portions 1 will eject the buttons to a disconnected position.

As a means of causing the two locking or latching elements 2 to expand or ride over the stud-portion when the buttons are in registration and are pressed together, two more abrupt inclined or flanged portions 1 are formed intermediate the relatively fiat WGd G'ShZL ed )ortions l said rounded ora: l a

tions 1 terminating at their base portions in slots 1 and forming a nose portion 1 to enter between the barsQ when the but- 7 tons are in registration and pressed together. As a means of conveniently indicating the'relative positions of the button members with respect to the locking and unlocking positions thereof, the button and base portions are preferably ofelongated or irregular form, asshown, this form also more securely holding the buttons in position in the button-holes of the cuff.

Having thus described one of the embodiments of our invention, without having attempted to set forth all the forms in which it may be made, or all the modes of its use, what we claim and desire to secure by Letters Patent is, V a
